Refiling of application Serial No. 756,688, fi1ed March 25, 1913. This application filed July 28, 1919.

Serial no. 313,927.

To eZZ whom it may concern Be it known that l, Crnnnnor, Leon-Davis, a citizen of the United States, residing at the borough of Brooklyn, in the county of Kings and city and State of New York, have invented certain new and useful improvements in Automatic Fire Extinguishers for Distributing- AQUGOLIS-Lllifl Fluent Material, of which the following is a specification.

The device shown, described and claimed herein, is a modification of the particular type of automatic fire extinguishers shown and broadly claimed in my co-pending ap plication Serial No. 313,926, filed July 28, 1919, of even date herewith, and shows an application of the broad principle shown, described and claimed in said aforesaid application No. 813,926, which is applicable so far as such broad principles are concerned for use with both finely comminutedcsolid materials, and with liquids also the particular device herein shown, described and claimed. while not limited strictly, especially in the broad claims hereof, thereto, being particularly designed, and especially adapted for use in distributing upon the adjacent fire zone a-fiuidal fire-extinguishing material of liquid and watery form; upon the thermal actuation of a suitable thermo-trip, the release of which (usually when the surrounding temperature reaches 155 degrees.

Fahrenheit) causes expulsion of the liquid in a forcible manner, by reason of the pendulous, rotative, nutative, and gyratory movements which the device performs upon such release; such expulsion being practically uniform thruout all dimensions of space. whereby the adjacent floor and ceiling, (and if the apartment be small, the walls also) will have every portion of their surfaces wetted with the fire extinguishing liquid: which may be of any kind, such for instance as carbon tetrachloride (GU1 solutions containing the same, or any liquid aqueous like fluent material carrying; firel-xilling; gases or like granulated solids held in suspension: including those forming a blanketing foam when projected into the firezone; all which hold to be within the meaning; and scope, ofthe wor s: llgjllCltion of the same, also in section on the line (t(b or Figure l, the motor-spring being,

Referring" to the drawing:

The reference letter A designates the gyroscopic-frame, revolubly supported in which is the receptacle The frame A is usually formed of metal cast or drop-forged into proper form, and suve for minor.clifferences is essentially-the saline as the like frame shown and described in my before mentioned moo-pending generic application. The liquid receptacle i s preferablypf the frustro-conical form indicated in Fig. l, and formed of suitable sheet metal. For convenlence of assembling, as hereinafter more fully described, the top-plate and the annular wall. are usually formed integral, and the bottom-plate is secured to the annular wall '7 by any suitable liquid tight joint, many of which are well known in the art.

As shown in Figs. 1 and 2, the bottomplate of the receptacle is dished inward at the center so as to form a cylindrical chamber to receive the coil-motor-spring E. F it" ting in this cylindrical chamber is the supporting-spider D, composed of the topplate 150. having the central boss S, 1), and the standards 151, extending at a right angle to 150. from which extend radially outward, (Figs. 1 and the receptacle supporting spider-arms 66, ending in the upturned closure-ringsecuring lugs 110 (Figs. 1 and 2) the office of which is to hold the annular closure-carrying-ring 5, in

' position upon the receptacle so as to be capable of vibration thereon. I p

The spider arm or bar 66, (on the side which is at the left. of Fig. 1) is provided with a depending lug. or lock-fin '66, which abuts against the upper end of the rocking-trip-lever 67, of the thermo-trip, the sccuring-main-plate of which is secured on what in Fig. 1, is the rear side of the bottom-bar f the frame by screws passinginto the same at the points indicated by 67, though in the drawing in Fig. 1

the frame A, and such main-plate are both partially broken away, in order to show how the trip-lever 67, rests against a rock knife-edged-lug 69, at the rear of a slot pentoward what is the left of Fig. 1. Such trip-lever is secured in such slot by an easily fusible solder usually that used in fire-extinguishing apparatus for their thermotrips, which melts at about 155 F.) which solderin order to more clearly show the construction, is in the drawing not shown. To the lower end of such rocking-trip-lever 67, is firmly secured in any desired manner the end of the secondary supportingtrip-cable 70, a loop of which is secured to the rocking trip+lever a short distance above the lower end by the same easily fusible solder, as indicated at 63; which releasing first adds a thrust of greater power to the trip-lever as the device falls upon the melting of both solders. However, as Ido not claim such trip specifically herein even in combination, the same having been so claimed in my c0- pending generic application herein referred to, I have not deemed it essential to more specifically show or describe s'uch thermotrip G'her'ein, nor several other parts,

- he receptacle 'B'is pivotally suppoi'ted in the frame A by suitable pivot 3ins 3'T and we fee th abf slwai i pesiuon top and" hotof course made liquid tight, in any suitable manner; and in order to lessen friction the bearings are usually provided with sleeves and washers of any suitable anti-friction material, such as plumbago composition, lo cated' at proper points, as clearly indicated in Fig. 1.

The lower pivot-pin 37 is formed integral with the motor-spring shaft F, while the upper pivot-pin 51, with an enlarged upper portion 52 which may be formed integral therewith, r which may (as shown in Fig. 1) be in the form of a sleeve having the upper flange 5%, such sleeve being secured to 51 by the drive-pin 52, and held against removal from the frame A by the securingpin 53; the purpose of 52' being to act as a protective dust cover for the upper bearing 105 when in position, and when withdrawn with the pin 51, to leave suflicient space between the top of the receptacle and the topbar of the frame A, to permit the receptacle to be slipped sideways into -.tne frame over the upwardly extemling square drive-stud 112, of the pawl-carrying-plate 113, of the motor-spring winding mechanism, and dropped back into the windingposition with such drive-stud 112 located in the like shaped cavity formed to receive it in the lower end of the motor-spring shaft F.

The coil motor-spring E is secured a the inner end to the motor-spring shaft F, by a screw or stud 36"passing thru a suitable slot formed in the spring, and the outer end is slotted s as to slip over a securing-stud 36 on the side-bar 151 of the supportingspider D; which stud 36 is so shaped as to slip out of the slot when the spring has reached the limit of its unwinding; the outer end thereof being curved inward at 15 5 (Fig. 2) and so shaped that when so released its own resiliency will force it into the position shown in dotted lines, with such curved end portion in contact with the next inward coil. When the motonspring and its shaft are placed in position in the motor spring chamber.v a split-plate 109 (Fig. 1) is used t close such chamber against dust. which is secured in place by screws 109; and revolublymounted in such plate 109, and in the circular top-plate 150 of the sup portingspider D in suitable journal-boxes (not shown) formed therein, and located. adjacent to the peripheral wall. of the springchamber. are a plmi'ality of anti-friction rollers with which the outer coil the spring contacts when unwound and released, so as to keep the spring out ofcontact with the walls of the spring chamber, and the secu stud 36 thus perm'ittihg" the reach tacle to there'a f .1" continii'ein' rotationby its own inertia; the curved end portion 155 of the motor-spring causing the rollers to ride easily thereover. By this construction the time of rotation of the receptacle will be materially increased.

Of course it is understood that the drawing of the motor-spring E is intended to be only diagrammatic, and that in practice the same has a much larger number of coils than are shown; and that the rollers 150 are f sufficient diameter to keep the spring from rubbing against the securing-stud 36, when once released therefrom, although in Fig. 2 such stud is shown somewhat exaggerated in length.

Revoluhly mounted in a cavity formed to receive it in the central enlarged boss-portion 120 at the center of the bottom-bar of the gyroscopic-frame A, is the motor-spring winding-ratchet mechanism, comprising the upper pawl carrying-plate 113, the cylindrical journal portion 114, and thesquare shaped drive-studs 116, and 112, all formed of one piece of metal. The cavity in theinner side of the boss is provided with the ratchet-cavities 121 at the periphery, to receive the outer ends of the spring actuated pawl-bolts 119 reciprocating in suitable chambers formed in the pawl-carrying-plate (Figs. 1 and 5). The lower end of the motor-springshaft F is sufiiciently large of diameter to cover and conceal the plate 113, and thus protect the ratchet mechanism from dust, and is provided with a central cavity to receive the drive-stud 112 so that rotation of the plate 113 will rotate such shaft F, and thus wind up the spring E, when such plate is rotated by the combined turn-nut and trip-cable fork 118, secured upon the bottom drive-stud 116 by the drivepin 117 (Fig.1) and after the motor-spring has been fully wound up the ratchet-plate may be further locked against movement by a set-screw 122, (Fig. 5) in order that the contact of the secondary trip-cable (Fig. 8) with the fork of the turn-nut when the device is suspended, may not further rotate the same. Such fork is preferable to a ring in that it allows of quicker release of the trip-cable from the frame upon the actuation of the thermo-trip, while at the same time acting equally well to hold the device in position ready to be actuated.

During the winding up of the motormechanism so as to cause rotation of the receptacle within the frame, and simultaneous vibration upon the main support.

In any event, upon the thermal release of the thermo-trip, the rocking trip-lever 67, will be wholly drawn away and out of contact with the receptacle and frame, and left suspended in the position shown in dotted lines in Fig. 8 in the secondary supportTO, the trip-cable 70 being for that purpose provided with a suitable end weight and center stop, as clearly indicated in such Fig. 8.

Surrounding the receptacle at the base is the closure carrying-ring 5 kept spaced outward therefrom by the slip-springs 111 (Fig. 2), thru orifices 129 inwhich ring project outwardly the delivery nozzles 126, thru which the fire-extinguishing liquid material is ejected; and secured to such ring 5 by rivets 132 and projecting out thru the orifices 129 are the stopper carrying-springs 131, each carrying at its outer end a closurestopper 130, which normally closes (Figs. 2 and 6) the substantially circular or cylindrical outlet orifice 127 in the nozzle 126, which is usually in the form of a cap screwed on the outer end of the deliverypipes 123 and 123', which preferably pass thru an angular sleeve 125 provided with the innerflange 124;. The joints between such flange and the receptacle wall Z, and the exterior of the outlet pipes are usually made liquid tight by soldering; and a suitable washer 128 (Fig. 6) is usually interposed between the outer end of the sleeve 125 and the innerend of the nozzle-cap.

The stopper-carrying springs 131 are each provided with a nozzle-slot 129, (Figs. 3 and 6): so that when the closure carryingring 5 is vibrated to the left (as indicated by the arrow in Fig. 6). the springs will be forced by their own resiliency back into the position shown in dotted lines, with the nozzles projecting out thru the slots and with their outlet orifices uncovered, so as to per mit of free flow of the liquid therethru. The closure carrying-ring 5 preferably held against accidental upward displaces ment by'having the upward extensions 110 of the supporting spider l) bent slightly iii-- ward at the top after the insertion of the ring in place, as clearly shown'in 1.

So far as ejectionof the liquid con-- ccrned, the outlet pipes migit just as well be merely short nozzles ending just within the receptacle wall, to the inner ends of which the liquid will be directed by the deflecting-vanes 35 and 95 upon the rotation of the receptacle, but in order to pre ent leakage thru such outlets during the long period during which the device will ordinarily be suspended in position ready for use, and also to prevent permanent sealing of the stoppers to the outlet orifices by pos: sible, corrosion, or chemical action of the contained liquid, which would render the lug 110, and the ring 5.

pivot-stud or bolt 135.

device inoperative when thermally released, I prefer to provide means whereby the liquid will not be in contact with the outlet orifices until the device is put into actuation; and a good and eflicient device for bringing about this result is to extend the outlet pipes 123 and 123, around the receptacle wall within the same adjacent to the base, slightly less than half of the circumference, (Fig.

so that when the device is suspended ready for use (Fig. 8) with what is the right side of Figs. 1 and 2 at the top, the level of the liquid in the receptacle will be as indicated by the line f--f of Figs. 1 andfl, and when in such position the pipe 123 having been drained of whatever liquid may have flowed into the same while being placed in position, etc, by merely forcing the stopper away from the nozzle, and then properly tensioning its stopper-spring by turning the tension-screw it will be seen that there will be no liquid at all in the pipe 123 and none in the pipe adjacent to the nozzle; and yet that upon the release of the device from the trip-cable 70, and its consequent rotation, both pipes will be instantly flooded,

and the liuid directed out thru the same by the deflecting-vanes 95 and 95, which are usually and preferably of substantially the curved shape clearly indicated in Fig. 2, so as to direct the liquid into the inner open ends of such pipes, as indicated at 96 of Fig. 2, and out thru the outer.

Secured to the peripheral wall of the receptacle is a short stud-shaft 137 (Fig. 1), on which is vibratorily secured, usually by means of a screw 137, the closure carrying-ring actuating lever or rock-bar 136, in actuating connection with such ring at the lower end and by means of a screw 138,

passing thru a slot in such lever and screwinc; firmly into the adjacent splder securing is provided at the top with the outwardly extending fork portion 135, in which slides easily up and down the downwardly pro ectins: lever actuating-lug 91, of the resilient spring trip lever 26, vibratorily secured to the top of the receptacle B by means of the. This trip levei. 26 is normally held against its own resiliency in the raised position shown in full lines in Fig. l, by the short quadra11t-rail. or stud 50 secured to the receptacle top; and whcn the device is wound up and ready for actuation, the projecting contact portion 90 of such trip-lever 26 lies on what is the rear side of the frame A, in Fi 1.behu1d the inward ly projecting corner trip-lug 510 formed integral with the frai'ue A, and in the position as indicated. in full lines in Fig. 1, which shows the same as it is just about to contact with such trip-lug 90 after the re ce'pta'cle hasbeen put into rotation upon the release of the thereto-trip G, and has.

he rock-bar 136- made nearly a complete revolution. As 90 comes into contact with 90 it is stopped and the receptacle continues to rotate, whereby the rock-bar 136 is vibrated so as to partially rotate the closure carrying-ring 5, whereby the stoppers are removed from the outlet nozzles, as shown indotted-lines in Fig. 6, and at this instant the lever 26 passing off from the rail or stud 50 such lever is by its own resiliency forced down into the position shown in dotted lines (Fig. 1) so as to clear the trip-lug 90, after which such lever 26 will of course move with the receptacle.

Located near the top of the receptacle adjacent to the upper end of the lever or rock-bar 136, is the combined filling and air-inlet orifice, which as shown in detail in Fig. 4;, is usually provided with an outwardly screw-threaded bushing 139, soldered or brazed in position in the receptacle wallT, on which is the washer 141, down on which is firmly screwed the inlet-cap 1&0, provided with the orifice 142, normally closed by the inlet-stopper 143, carried by the straight spring 144 secured to the lever 136, so that the vibration thereof will open the air-inlet orifice simultaneously with the opening of the outlet nozzles, upon the vibration of 136, as hereinbefore described.

For convenience in shipping filled, and in filling or refilling the receptacle the frame A. is usually provided with three projecting feet or lugs indicated by 1&6 and 146, which together thus form practically a supporting, tripod at the side that is the left of Figs. 1 and 2, which lugs or feet may be formed in tcgral with such frame, or secured thereto by screws 14:7.

The main support which allows the frame A to'gravita-tionally vibrate when released thermally, is preferably a flexible one, and in practice I have found a chain support 10, secured to a main supporting ring-bolt 10', affi'xed to the ceiling at the upper end, and to a supporting-ring 51' formed integral with the upper pivot-pin 51, to be highly eflicient. In some cases, however, and where the device is of large size and consequent great weight, to avoid danger of breaking the supporting chain as the same is twisted during the actuation of the device, a swiveljoint or link 9 (Fig. 1) is located therein of considerable retarding frictional power, sufficient to permit of the twisting up of the chain so as to raise the device, and to thereafter swivel sufiiciently to prevent the inertia of such heavy receptacle from breaking such chain; which swivel-joint or link 9, is preferably connected with the supporting-ring and pintle pin, as shown. And with the ordinary chain-swivels of commerce, I have found that while the same lessens it does not prevent wholly the twisting and untwisting of the chainduriiigrotation, whereby a consequent rising and falling, and gymtory pendulous motion is given to the entire device during operation,' which results in equably distributing the contained liquid in all direct-ions surrounding the main suspension point 10 which will be itself deluged; whereby adjacent fire wherever located will be extinguished.

While the main-plate of the thermo-trip G, shown in Fig. 1, which carries the rocking trip-lever 67 is usually located on what would be the rear side of the gyroscopicframe A, as shown in Fig. 1, and firmly screwed in position by two suitable screw bolts passing thru the two holes shown in the bottom bar of the frame and screwing into such main plate, any other suitable means of securing such thermo-trip G in position may be used.

I do not intend to limit myself to the exact form of construction herein set forth, as many changes and modifications to adapt the device to particular uses may be made Without departing from the scope of my invention; such for instance as'changing the shape or number or position of the outlet orifices, or of the air inlet orifices; and Wherever I have in the claims hereof used the singular number in referring to any element, I intend to cover and include thereby any desired plural number as well.
